Well, anytime you can trade a guy with one functioning ACL for a guy with two, you have to do it.

That’s obviously an oversimplification of things, but it’s hard to argue with the logic. The Boston Celtics needed a body in the backcourt, and to get it, they traded a player who was no longer of any use to the team.

The official deal has been reported as follows. The Boston Celtics will acquire guard Jordan Crawford from the Washington Wizards for the expiring minimum contract of Leandro Barbosa, according to Adrian Wojnarowski:

It’s a curious trade for Washington, if only because Barbosa is out for the season with a torn ACL. After previous reports had the Wizards landing rookie center Fab Melo from Boston, you’d like to think they could have squeezed a second round pick or something they could use going forward. Since Barbosa is on an expiring deal, the chances he re-signs as a free agent in Washington are slim and none. This is a straight player dump.

The Wizards must feel like this is addition by subtraction, and the further cleansing of an old era of Wizards basketball. Crawford is a bit of a knucklehead — you may remember him for hits like, “I feel I can be better than Michael Jordan” and his obsession with his “steez” — but his on court play is probably more destructive than his sometimes peculiar behavior. Crawford is a career 40 percent shooter from the field and a sub 30 percent 3-point shooter, but that hasn’t stopped him from firing up a whopping 17.3 attempts per36 minutes over his career.

While Barbosa used 21.4 percent of Boston’s possessions this year, Crawford has used 27.3 percent over his career. It might take some time for Crawford to get used to less minutes (he averaged 26 a game with Washington) and less shots, but he has to be excited for the shot at reforming his image in one of the most veteran heavy locker rooms in the league.

Crawford is still just 24, he’s a former first round pick, and he does have talent. His raw per36 numbers of 18.1 points, 5 assists, and 4.3 rebounds are only matched by a handful of players in the league, but we’ve still yet to see if Crawford can turn off the part of his brain that tells him to take horrible, horrible shots. He’ll have to do that first to take any significant playing time from Avery Bradley, Jason Terry and Courtney Lee.

For Boston, it’s a low-risk move since they aren’t sacrificing anything of use to them this year or down the line. Crawford is set to make $2.1 million next season, so the Celtics are essentially betting $1.3 million dollars of next year’s budget (the difference between a minimum contract and Crawford’s) that Crawford can help add backcourt scoring pop and depth. That seems like a bet worth making.

For Washington, it’s a bit disappointing. Crawford should have been able to net something of value in return, and Barbosa will never put on a Wizards jersey. Cleaning house is never as easy as it seems, but it’s still hard to comprehend the urgency to move Crawford for absolutely nothing.

Update: Celtics center Jason Collins will also go to Washington as part of the deal.

This means Motiejunas can’t sign with the Nets, who signed him to the original offer sheet, for one year.

I bet it also means Motiejunas and Houston have agreed to a new contract. Otherwise, why release him from the offer sheet? The Rockets would be giving up a tremendous amount of leverage out of the goodness of their hearts – unless this is just a prelude to a new deal with Houston.

DeMar DeRozan is having one of those seasons for the No. 2 team in the Eastern Conference, the Toronto Raptors. During Thursday night’s win over the Minnesota Timberwolves, 124-110, DeRozan scored 27 points while adding eight rebounds, five assists, and shooting a whopping 13 free throws.

DeRozan also sealed the victory in the final minute with a huge put back dunk.

The Raptors led by 9 points with a minute left as they were inbounding the ball. A long pass from the baseline to a streaking DeMarre Carroll resulted in a blocked layup, but DeRozan was there to clean up the mess.

Here’s what you missed Thursday around the NBA while you were drinking homemade glow-in-the-dark beer with jellyfish genes in it (no, you try it first, I insist)…
1) Don’t play Memphis in a close game, they just find a way to win. Last week, when Mike Conley went down with a back injury and was going to miss six weeks (give or take), we questioned if Memphis could keep their heads above water. They promptly went out and lost to a very good Toronto team.

Since then they have won five in a row, capped by an impressive 88-86 win over Portland Tuesday. Impressive because:

• Memphis is now 12-0 in games that were within 3 points in the final minute. You get in a close game with Memphis, you lose. (Statistically, we know some of that is luck, that there will be some regression to the mean, but that stat has propelled a team has been outscored by nine points this season, one that should be 12-12, to the 16-8 record they have.)

• Memphis trailed Portland 79-68 with less than five minutes to go, and still won.

• Marc Gasol had 36 points and has been an absolute beast since Conley went down, doing whatever it takes to win.

• Toney Douglas — a guy the Grizzlies just picked up off the street this week, basically — comes in and is clutch down the stretch for them, including hitting the game-winning free throws with 0.5 seconds left (Damian Lillard tried to argue the call, to no avail).

The schedule gets tough for Memphis the next couple of weeks — Golden State, home-and-home with Cleveland, then Boston and Utah looming not long after — but do not doubt the Grizzlies. No team is as resilient as this bunch.

2) Bulls prove Spurs aren’t perfect on the road. It was bound to happen, the San Antonio Spurs were 13-0 on the road, they were going to stumble at some point. That point turned out to be Thursday night in Chicago, where the Spurs came out of the gate like they went out and had a big pregame meal of Lou Malnati’s pizza — 32 points on 30.6 percent shooting in the first half for San Antonio. The Spurs didn’t defend poorly, for example Kawhi Leonard held Jimmy Butler to no first-half points — in fact, midway through the first quarter Taj Gibson and Robin Lopez had scored almost all the Bulls’ buckets — but the San Antonio offense was dreadful. Throw a little credit to the Chicago defense if you want, but this was more San Antonio stumbling than a Chicago return to the Thibodeau era.

The Bulls were up 12 at the half and were able to hang on despite a strong second 24 minutes from Leonard (17 of his 24 came in the second half) and get the win. Dwyane Wade had 20 points and hit a couple of key buckets late to stabilize Chicago. For a Bulls team that is going to be in a playoff battle all season — they are the seven seed right now, one game ahead of the Pacers in ninth — these kinds of wins at home can prove huge.

3) What is it with Minnesota and second half? On the road, the Minnesota Timberwolves had played the Toronto Raptors even for the first 24 minutes — it was 59-59 at the half. And yet, there was a sense of dread for Timberwolves fans because all season their young team has just come apart in the third quarter — and then Toronto opened the second half on an 11-2 run. Minnesota, to their credit, crawls back into it, but midway through the fourth the Raptors go on a 17-4 run sparked by Kyle Lowry and DeMar DeRozan, and the Raptors pull away for the 124-110 win. The Timberwolves lost another game because they can’t defend well.

Minnesota shows flashes of the kind of brilliance that has everyone thinking they might be a contender in a few years. But we all expected too much too soon from this group. Those impressive stretches are followed by ones where they play like a young team, they don’t defend well, and they throw those good efforts away. Not that they were going to beat a good Toronto team on the road, but the Timberwolves can be frustrating to watch. Patience is hard, and Minnesota fans are being asked to show a lot of it. We can debate if it’s time to bring Ricky Rubio off the bench and let Kris Dunn sink or swim, but that’s not the core problem. Ultimately, the Timberwolves are young and playing like it. They don’t know how and aren’t putting in the effort to defend well yet. Karl-Anthony Towns, Andrew Wiggins, Zach LaVine, they can be the core of a contender eventually, but there is a lot of learning to do along the way. Tom Thibodeau can teach them. But it’s going to require patience.
